Abstract
The objectives of this work were to assess the ability of the 10-parameter model, examined in Part 1 of the study, to represent hindcast directional wave spectra and to provide an appraisal of how well the ODGP hindcast model predicted existing WAVEC observations. The parametric model acceptably reproduced the hindcast spectra over 90% of the time, with nearly 70% of the records having residual errors of less than 10%. There was little loss of information as indicated by the behavior of selected spectral statistics. A comparison of the hindcast spectra with field observations showed a significant correlation between energy levels, peak wave direction and vector mean direction. The hindcast directional peaks appeared to be generally sharper than the field data. No definite conclusions could be formed on specific frequency-direction features due to intrinsic limitations in directional spectra techniques.
